BABROWS AND GEORGE w. LANGFORD, OF ANN ARBOR, MICHIGAN, es- SIGNORS T ECONOMY BALER COMPANY, or ANN ARBOR, MICHIGAN, a CORPORA- "rIoN OF MICHIGAN BALING PRESS Application filed July 18,

i The invention relates to baling presses of that type having longitudinally extending slots inits end walls through which the'bar a of the compressing, plunger extends. The invention has for its main object the provision of means for closing the slots to prevent the material within the baling chamber from being forced therethrough. The invention'has for another object the provision of slot closure means, which is movable'upon movement ofthe compressing plunger to allow-movement of the compressing plunger bar. l/Vith these as well as other objects in View, the invention resides in the novel fea- 1 tures of construction and combinations 'and arrangements of parts as more fully herein after set forth.

In the drawings Figure 1 is a diagrammatic end elevation of a'baling press, embodying our invention; Figures 2 and 3 are cross sectionsyrespec tively, on the lines 2-2 and 3-3 of Figure 1; Figures 4:, 5 and 7 are views similar to Figure 1, showing modified constructions; Figure 6 is a cross section on the line 6-6 of Figure 5; I r Figure 8 is a cross section on the line 8-.8 ofFigure 7; 1 l a Figure 9 is a view similar to Figure 2, showing a modified construction; 7 Figure 10 is'an end elevation of a portion thereof. 1 7

As shown in Figures 1, 2 and 3, 1 is the baling chamber of the baling press, which is specifically formed by the doors 2 pivotally mountedupon the stationary'end wall 3, the doors having the transverse portions 4 at their free ends together forming the opposite,

end wall of the baling chamber. The stationary end wall 3'has the central longitudinally extending slot 5, while the portions 4 of the doors terminate short of each other to form the central longitudinally extending slot 6 in the opposite end wall. 7 is the compressing plunger, which is movable longitudinally within the baling chamber 1 and in the present instanceis movable downwardly toward the stationary platen to compressthe material within the baling chamber. This plunger is mounted upon the plunger bar 8, which 1927. Serial No. 206,647.

extends through the slots 5 and 6 of the bal-. ing chamber and is actuated by suitable means such as the chain 9at each end of the baling chamber and outside the same, and extending over the wheels .10 and 11', respectively, at the upper and lower'ends of th i g chamber, the latter wheel being preferably power driven. The arrangementis suchthat upon upward movement of the plunger it will be carried upwardly from the balingchamher and tilted to permit the material to be compressed to be thrown into the baling chamber through itsupper end.

For the purpose of'preventing' the material withinthe baling chamber from passing out through the slots 5 and 6 or being forced outwardly through these slots during the compression movement-of the compressing plunger, we have provided the flexible meme ber 12 which extends longitudinally within each of the slots and around the wheels 13 and 14, respectively, at the upper and lower ends of the baling chamber. Thisfiexible connection is preferably acable of a diameter substantially equal to the width of either slotand having its ends connected to the plunger bar 8 so that it. moves with theplunger bar and will not interfere with the movement of the latter in the slots. 1

In the modification shown in Figure 4, the baling press is of the upstroke type, in which the compressing plunger 15 is movable upwardly toward the platen to compress the material within the baling chamber. The arrangement of the compressing plunger bar and actuating means is the same in both instances. However, in this baling press the exten'din '27 by means of the clevises 28.

actuated by a counterweight which should be sufiiciently heavy to maintain the slot closure means taut.

Figures 5 and 6 disclose another modification of baling press which, as specifically shown, has the san e general arrangement of parts asthe baling press of Figures 1, 2 and 3, with the exception that the slot closure means is different.

longitudinally oft-he balingchamber at each of its ends and adapted to register with a longitudinally extending slot of the baling chamber. This bar is located adjacent the outer edge of the slot and is nor-- mally held in registration with the slot by means of the levers 20 and 21, which have their'inner ends pivotally connected respectivelyio the upper and lower ends of the closurebar and their outer ends connected to the coil springsn22, these levers being pivotally 1 mounted intermediate their ends upon the end walls of the baling chamber. The upperinner edge of each closure bar 19 is canimedas at'23 for engagement with the compr ssingplunger bar when lowered, so that this latter bar will gradually -force the closure bar out of registration with the slot, at which time the closure bar pivots about the lower lever 21. Theclosure bar also has its-lowerinner edge cammed for engagement'with thecompressing plunger bar, it used in an upstroke t pe baling press.

"In the modification shown in Figures 7 and 8, the slot closure means is still different, it includingtheseries of pivotally connected fiat links 24, which normally register with each slot at its outer edge, each link being held -in this position as-by means ofthe coil spring 25. The linlrs extend upwardly above the baling chamber so that the uppermost link clears the compressing plunger bar when tilted, so that when the compressing plunger is lowered its bar comes successively into engagement with the links to laterally force the same-out of registration with the slot.

' Figures 9 and lO illustrate another modification of baling press which, as-specifically shown, is of theupstroke typehaving the compressin plunger 26 movable upwardly within" the baling chamber 2'? and toward the stationary platen to compress the material within this baling chamber. The plunger bar of the compressing plunger extends through the vertically extenning slots in the oppositeend walls 'of'the baling chamber in the same manner as those previously described audits ends are connected to chains For preventing material within the baling chamber from passing out through the slots of the baling chamber or being forced outwardly through these slots during the conun'essing move ment oi: the compressing plunger, tnere is the flexibl connection 29, preferably a cable,

for each slot. The upper end of each cable 19 is a slot closure bar is secured to the frame of the baling press in a manner to extend longitudinally within each slot and close the same downwardly to the plunger bar. The cable then passes around the sheaves 31 and 32, which are connected-to the plunger bar and are located thereabove, the sheave 32 preferably extending between the bifurcations of the clevis 28. The cable then extends downwardly to near the bottom of the bnling press frame, to which it is connected by. means of the coil spring 83, which is suiiiciently strong to maintain the cable taut at all times. The sheave 81 is located to extend within the slot at that end of the b'aling chamber and as a resultthe portion ofthe cable on thecompressing side of the compressing plunger or in the present instance above the compressing plunger is always located in the slot.
